Director Dean Fleischer-Camp’s novel stop-motion meets live-action dramedy Marcel the Shell with Shoes On (B) is an often entertaining sass menagerie, the A24 Films indie improv build on the likes of Aardman Studios’ Wallace and Gromit clay-making charm with a mix of Pixar-style pathos to punctuate the proceedings. This mockumentary style slip of a story is based on a series of online webisodes and stars the voice of Jenny Slate as the titular anthropomorphic animated character. Marcel lives with his grandmother (dialogue by Isabella Rossellini) in a vacation rental home occupied by a human filmmaker, played by the actual director. Viewers are treated to the one-inch-tall protagonist’s misadventures, gallant gadgetry and droll quips inside the house as he prepares for a newsmagazine TV show to chronicle his quirky life and possibly reunite him with his conch kind. Enjoyment of this movie depends on how captivated you are by Marcel; and while this shell without a filter is indeed hella funny, an elongated series of his outtakes do not a full-fledged story make. The film gets high originality points for its pleasant change of perspective amidst flashier fare. If you listen closely, you may hear tremendous tidal tidings washing over you, but some of the time it’s just treading water.
